So I'm using UNF to research keywords and I'm wondering how accurate the competition analysis is. Like I'm finding a lot of longtails between 30-40 difficulty but when I search the front page is dominated by amazon, wikipedia, ehow, about.com etc. How hard is it to compete with these sites? I'm having trouble with the search function its giving me an error. Total noob here. Also how accurate is serpiq in determining difficulty of competition?
